Hi Frederic,
Thank you for your post.
It is most commonly due to an installation error where you may have run the “Network” option instead of “Standalone / Educational (Run with a local standalone database)”. Firstly, completely uninstall iTWO costX from your current computer, including selecting ‘No’ when asked if you wish to keep the database. Then reinstall iTWO costX with the “Standalone / Educational (Run with a local standalone database)” option, which appears during the installation process.
Kindly inform you that please you could refer to our Student FAQ as it will help to answer most of your questions. https://education.itwocostx.com/support/forum/student-faq/
